I think you mean 716 irons.  The 714 irons were released in early November of 2013, so I would assume that the 716s would follow the same time frame, November 2015.  Pre-orders would probably be a few weeks prior to that.    When I pre-ordered mine, I could not have them until the official release date.  Well worth the wait.  

For anyone coming from much earlier generations or switching to Titleist all together, Im sure they are gonna be great, but for those of us who are on 714's its going to be hard to improve on an already "perfect" iron!

Titleist Loyalist through and through.
